The Irrigation Sprinkler System Activation & Start-Up procedure has several steps. This prepares your system for the watering season. First, you thoroughly inspect all components. This includes the backflow preventer, valves, and sprinkler heads. You check for any leaks, blockages, or damage. Next, you turn on the water supply smoothly. This prevents the water pressure from increasing. You also check the connections for leaks. Then, you set the system pressure to the recommended levels. You program the controller with the right date, time, and watering schedule. Each sprinkler head is cleaned, aligned, and tested. This ensures even water distribution. You check the different zones one by one to see how they perform. If your system has drip irrigation, you check the emitters for clogs or damage. Finally, you calibrate the rain sensor or weather-based controller. This helps conserve water. By following this process, your irrigation system will work well all season.
